< characters and underscores.
Codec manufacturer (human readable).
|
inline |
Codec name (human readable).
|
inline |
Codec version (human readable).
|
inline |
See CODEC_TYPE_* defines above.
|
inline |
MIME subtype.
|
inline |
Number of elements in fmtps array. Set to 0 if codec does not need fmtp.
|
inline |
Array or recommended (supported) fmtp strings. Set to NULL if codec does not need fmtp.
|
inline |
Sample rate for the PCM data expected by the codec in samples per second. Only 8kHz, 16kHz and 32kHz sample rates are supported.
|
inline |
Number of channels supported by the codec. Only single-channel codecs are supported.
|
inline |
See CODEC_FRAME_PACKING_* for details.
|
inline |
Minimum bit rate for this codec (in bits per second).
|
inline |
Maximum bit rate for this codec (in bits per second).
|
inline |
Number of PCM samples per input frame for frame-based codecs. For sample-based codecs should be equal to number of samples to generate integer number of bytes of encoded data (e.g. 1 for G.711, 2 for G.726-32, 4 for G.726-16, etc).
|
inline |
Minimum number of bytes produced after encoding numSamplesPerFrame samples of PCM data.
|
inline |
Maximum number of bytes produced after encoding numSamplesPerFrame samples of PCM data.
|
inline |
Algorithmic delay (samples) of this encoder/decoder. Also known as codec lookahead. This should not include packaging delay (which equals to codec packet size). It will be taken into account independently. Counted in samples.
|
inline |
TRUE if codec could carry DTMF tones, FALSE otherwise.
